ripple-tank interference lab
A GPU wave-equation ripple tank. Crests glow cyan, troughs violet; amber bars are solid barriers and the pale teal disk is a shallow lens that slows waves, bending their path.
Drag the water to stir · tap to drop a droplet · drag the glowing orbs to move the sources · tap an orb to mute it · right-drag / two-finger to orbit · wheel to zoom.
1–6 presets · Space pause · C clear · R rain · M sound · S snapshot · Q quality · H help
Presets explore the classics: open ripples, two-source interference, double-slit diffraction, lens refraction, lattice scattering and a focusing echo basin.
